What
Some Claude Code dialogs have tabs along the top. The row of tabs now wraps onto extra lines when the window is too narrow, and the dialog title no longer shrinks to make room. The dialog now sizes itself using the header's real height instead of assuming two rows. Content inside a tab can also now take over the arrow keys that normally move between tabs.
Why
Settings, plugins and similar tabbed panels should stop cutting off tabs in narrow terminal windows.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
It is not clear which dialogs let their content take over the arrow keys.
